The Connection between PCB, Electric Circuit Diagram, and Electronic Components
The wiring diagram and the netlist
Note
The electrical design of a PCB starts from the circuit diagram (SEF, Functional Electrical Diagram).
Whether it is made with Cadence OrCAD or with Mentor DxD, the electrical designer proceeds to study the electrical functionality to be created.
Once all the necessary components have been identified, the list of components (BOM, Bill Of Material) is drawn up for the purchase of the same.
The drafting of the electrical circuit diagram takes place at the same time as the BOM; first place the electrical symbols and then connect through the so-called "net".
Once the wiring diagram is frozen, the "netlist" is exported, a table representing the electrical connections present and the components used.
